The black cutworm is a serious crop pest. Phoxim, an organophosphorus insecticide, has been widely used to control . When phoxim is extensively applied, the susceptibility of to insecticide is reduced.
Glutathione S-transferases (GSTs) are crucial for detoxifying pesticides in insects, particularly in the economically important cigarette beetle (Lasioderma serricorne).
The study identified 14 GSTs in L. serricorne, with six genes significantly upregulated after exposure to the pyrethroid insecticide lambda-cyhalothrin (LCT), with LsGSTe1 showing the most substantial increase.
LsGSTe1 not only metabolizes LCT but also protects against oxidative stress; targeting this gene could enhance pest management strategies for controlling the cigarette beetle.
